This patch adds device tree and driver model watchdog support,
converts the legacy omap watchdog driver to driver model for
TI AM335x chipsets. The following compile warning is removed:
===================== WARNING ======================
This board does not use CONFIG_WDT (DM watchdog support).
Please update the board to use CONFIG_WDT before the
v2019.10 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================
CONFIG_HW_WATCHDOG is no more a default option for AM33XX devices
after DT/DM conversion, adjusted kconfig accordingly.
DM watchdog support is enabled by default in SPL. The SPL image
doesn't fit into SRAM because of size constraints and build breaks
with an overflow. For this reason DM watchdog support should be
disabled in SPL, driver code should be adjusted accordingly to serve
this purpose.
Built and tested on AM335x device (BeagleboneBlack), compile tested
for all other AM33xx based boards.

Avoid using a typedef here which is unnecessary. Add an 'env_' prefix to
both the enum and its members to make it clear that these are related to
the environment.
Add an ENV prefix to these two flags so that it is clear what they relate

U-Boot is not supposed to use typedef for structs anymore. Also this name
is the same as the ENTRY() macro used in assembler files, and 'entry'

This adds support for slave serial programming, in addition to the
previously supported slave SelectMAP mode. There are two ways that this
can be used:
-Using the clk and wdata callbacks in order to write image data one bit
at a time using pure bit-banging. This works, but is rather painfully
slow with typical image sizes.
-By specifying the wbulkdata callback instead, the image loading process
can be offloaded to SPI hardware. In this mode the clk and wdata
callbacks do not need to be specified. This allows the image to be
loaded much faster, taking only a few seconds with even relatively large
images.
Slave serial programming has been tested on the Kintex-7 series of
FPGAs.

Texas Instruments' K3 generation SoCs has specific modules/register
spaces used for configuring the various aspects of a remote processor.
These include power, reset, boot vector and other configuration features
specific to each compute processor present on the SoC. These registers
are managed by the System Controller such as DMSC on K3 AM65x SoCs.
The Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used to communicate to the System Controller from various compute
processors to invoke specific services provided by the firmware running
on the System Controller.
Add a common processor control interface header file that can be used by
multiple remoteproc drivers. The helper functions within this header file
abstract the various TI SCI protocol ops for the remoteproc drivers, and
allow them to request the System Controller to be able to program and
manage various remote processors on the SoC. The common macros required
by the R5 remoteproc driver were also added. The remoteproc drivers are
expected to manage the life-cycle of their ti_sci_proc_dev local
structures.

TISCI protocol supports for enabling the device either with exclusive
permissions for the requesting host or with sharing across the hosts.
There are certain devices which are exclusive to Linux context and
there are certain devices that are shared across different host contexts.
So add support for getting this information from DT by increasing
the power-domain cells to 2.
For keeping the DT backward compatibility intact, defaulting the
device permissions to set the exclusive flag set. In this case the
power-domain-cells is 1.

Any host while requesting for a device can request for its exclusive
access. If an exclusive permission is obtained then it is the host's
responsibility to release the device before the software entity on
the host completes its execution. Else any other host's request for
the device will be nacked. So add a command that releases all the
exclusive devices that is acquired by the current host. This should
be used with utmost care and can be called only at the end of the
execution.

Add and expose a new processor shutdown API that wraps the two TISCI
messages involved in initiating a core shutdown. The API will first
queue a message to have the DMSC wait for a certain processor boot
status to happen followed by a message to trigger the actual shutdown-
with both messages being sent without waiting or requesting for a
response. Note that the processor shutdown API call will need to be
followed up by user software placing the respective core into either
WFE or WFI mode.

Sysfw provides an option for requesting exclusive access for a
device using the flags MSG_FLAG_DEVICE_EXCLUSIVE. If this flag is
not used, the device is meant to be shared across hosts. Once a device
is requested from a host with this flag set, any request to this
device from a different host will be nacked by sysfw. Current tisci
driver enables this flag for every device requests. But this may not
be true for all the devices. So provide a separate commands in driver
for exclusive and shared device requests.

In the case of the tsec network driver, so far there has been no
mainline user of DM_ETH where the DT bindings get used.
In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string
was made up for the documentation, but there is no mainline code that
parses the "compatible" property anyway.
In both cases, there are no DT blobs that contain the old strings.
So change the documentation to "fsl,etsec2" for the Ethernet ports and
"fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also
uses, at least for LS1021A. More compatible strings can be added once
other (PowerPC) SoCs are migrated to DM_ETH.
The current ls1021a.dtsi doesn't match what was documented for the MDIO
buses anyway (the "compatible" is "gianfar" currently). This will be
fixed in the next patch.

By convention, the eTSEC MDIO controller nodes are defined in DT at
0x2d24000 and 0x2d50000, but actually U-Boot does not touch the
interrupt portion of the register map (MDIO_IEVENTM, MDIO_IMASKM,
MDIO_EMAPM).
That leaves only the MDIO bus registers (MDIO_MIIMCFG, MDIO_MIIMCOM,
MDIO_MIIMADD, MDIO_MIIMADD, MDIO_MIIMCON, MDIO_MIIMSTAT) which start at
the 0x520 offset.
So shift the DT-defined register map by the offset of MDIO_MIIMCFG when
